    1. Carbon hacking: Least carbon-intensive traveling between US and Europe

      My life is split between the US and the Netherlands, where I have friends and work in both places. I try to fly as little as possible: only one intercontinental flight per year. But even that puts my individual carbon footprint far above the average human's. I buy carbon offsets but that just shifts responsibility.

      I've long been deeply inspired by Greta Thunberg's protest act of sailing from England to New York to attend a 2019 climate summit. But sailing across the ocean in a racing yacht with a crew simply is too extreme.

      So I'm curious what are the options for reducing carbon emissions when traveling between continents.

      I've contemplated hopping on a freighter ship. My thinking is that: freighter ships are extremely efficient cargo-weight-to-emission ratio-wise, so the marginal carbon emission of me as added 'cargo' must be much lower than as another passenger on an airplane. Plus, the freighter ship will be sailing with or without me on board; whereas as a plane passenger I enable the business of a passenger flight.

    2. Commercial "foodcycler" devices - do they do more harm than good?

      Hello Tildes,

      I've been doing bokashi composting for pretty much all my vegetable and fruit scraps since last year. Lately, I've been wanting to level up my game and recycle meat scraps and chicken/fish bones as well. That's how I came across these "foodcycler" devices. They basically chop up and dry food scraps in a sealed container. I assume it works much like how industrial composting machines work, except it's scaled way down. At around 300-400 dollars, they're certainly not cheap, and probably generate a lot of greenhouse gasses during the manufacturing process. What's more is, every time you run a cycle, it has to run for 4-8 hours, though the manufacturer says the device is "energy conscious."

      I'm trying to assess whether I'll do more harm than good by buying one of these things to convert more of my food scraps. My ultimate goal is to try many different ways to recycle food waste and try to get my friends to try it out as well. Some of them have already shown interest in bokashi composting, but none has actually tried it out (too much work).

      Do you think commercial "foodcycler" devices do more harm than good? How should we go about evaluating this?

      Edit: I've asked this question on many different places, and it looks like the general consensus is there's no strong need for something like this unless you live in apartments, in a city/town that does not collect food waste. Some believe recycling food waste via the more traditional methods (e.g. bokashi, vermicomposting) would yield better results because the foodcycler would dry up and kill a lot of the bacterial presence, though I believe the dried up scraps can be somewhat "revived" by mixing them in wet soil. Nobody seems to be able to definitively tell whether using the foodcycler would be a net positive or negative, because there's no way to verify its manufacturing process. I may do an experiment on how much power it draws if I get my hands on one in the future.
